The Río Mayo titi[1] (Plecturocebus oenanthe), also known as the San Martín titi, is native to the San Martín region of Peru and is considered Peru’s most endangered primate.
- They live in low-lying secondary forests and are often seen in bamboo groves, fruit clusters, grape vines, and palm-dominated forests.
- At first glance, Río Mayo titi appears to have round, robust bodies. This is because their dense fur obscures their actual body shape and sometimes makes them look like growth on a branch – great for hiding from predators!
- They use a long, intangible tail to balance themselves on branches.
- They also have a variety of color types: individuals in the northern part of their range are more likely to have brown bodies with a white mask, while those in the south are more likely to have orange to dark brown bodies and no mask.
- Sometimes pairs of different colors have common offspring.
